. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. 156 I. Koslowski Life coloration: From observations of several adult males and females. Ground colour of adult males a metallic blue, brownish to olivaceous on nape and back, whitish in belly region. An orange—yellow area on lower operculum and on suboperculum, in some specimens reaching onto body, around pectoral fin base to about fourth vertical scale series behind the base. A lateral band running from eye to tail spot, but most of the time interrupted, then only distinct where crossed by bars. Tail spot most distinct marking in all moods. Bars sometimes visible, especially in aggressive specimens, most distinct above lateral band, bars 4—6 also visible below lateral band. Suborbital and superorbital stripe apparent most of the time, but fading in aggressive specimens. Cheek and gill-covers with lots of blue spots and stripes, some of them reaching into posteroventral orange—yellow area. Scales on nape dark brownish, with distinct light edges. Vertical abdominal stripes most distinct in aggressive specimens. Caudal fin dark greyish between rays, looking like horizontal stripes. Up to four light vertical stripes in posteriormost part and some light spots just behind tail spot. Dorsal fin dark greyish basally and at its edge, bluish in middle part. Anal fin similar. Soft part of anal and dorsal fin with light spots and stripes. One or two anterior dorsal fin spines and membranes black. Dark greyish fin coloration turning to reddish in aggressive specimens. Pelvic fins with a dark spine, bluish on first rays, transparent inwards, produced membrane with a white tip. Females: Dark markings similar to those of males. Ground colour greyish turning to yellow in prespawning phase. Orange—yellow colour on gill-cover and anterior body missing in females. Breeding pattern of females consisting of black suborbital stripe, black midventral s
